ARA: Where can I get my leather bag cleaned?

I usually am very fickle with my handbags, don’t spend a lot of money on them, and retire them after a season. However, this spring I indulged and bought myself a pricey white leather handbag. Since I consider this one an investment piece, I am looking for advice on how and/or where to clean my bag before I store it for the winter.

I definitely feel like this question has been asked on this forum. How to clean leather a million times over. Anyway, I second Colonial Cleaners, they send their stuff to SuedArt, the best suede and leather cleaning company I have ever seen.
